Swift the new Apple’s programming language my first review (in Spanish)
Few days ago, during the WWDC 2014, Apple released a totally new programming language to be another great option to Objective-C. This programming language was called Swift, so I started to review an learn what Swift offer us in the mobile world development.
I have to say it is really impressive, because it include a huge amount of new features (compared with Objective-C), in that sense Swift has a clearer, simpler and easier syntax; if you are a JavaScript, Python or Ruby developer you are going to find many similarities between Swift and those languages.
These are some useful links if you want to start learning Swift, enjoy them and remember be happy with your code!

Session 1 – jQuery coding conventions and best practices (in Spanish)
This is the first video of a new initiative where we are going to learn some coding conventions and best practices related with jQuery. It doesn’t matter if you already know jQuery syntax or how jQuery works, because if you want to become a great front-end developer you definitely need to follow coding conventions and also be worried about optimization in your JavaScript code.
So, let’s start with the first video. During this one we will see:
- What’s the best way to load jQuery
- What’s a Content Delivery Network (CDN)
- Which are the most used CDNs to load jQuery and their differences
- Writing a callback in case of the CDN doesn’t respond
- What’s a URL relative to protocol and how to use it
If this video likes you, please share with your friends and remember be happy with your code!
Introduction – jQuery coding conventions and best practices (in Spanish)
So, have you decided to use jQuery as one of your knights in your “chess-development-game”, then let me give you a gift today, this is a new series of videos where we are going to learn many jQuery coding conventions and best practices in order to show you how to become a awesome front-end developer!
This is the introduction to the course, I hope you enjoy it, and remember, be happy with your code!
Warning: strtotime(): It is not safe to rely on the system’s timezone settings in CakePHP SOLVED
If you are trying to run the CakePHP console from your command line, probably you are obtaining a warning related with the system’s timezone, that is a normal behavior if your web server doesn’t have a timezone configured correctly. Let’s see an example about this and how to solve it.
Problem
|
1 |
Warning: strtotime(): It is not safe to rely on the system's timezone settings. You are *required* to use the date.timezone setting or the date_default_timezone_set() function. In case you used any of those methods and you are still getting this warning, you most likely misspelled the timezone identifier. We selected the timezone 'UTC' for now, but please set date.timezone to select your timezone. in /Applications/XAMPP/xamppfiles/htdocs/projects/juan-nuevo/lib/Cake/Cache/CacheEngine.php on line 60 |
Solution
- Go to the core.php file in your CakePHP project, something like this: YOUR_SITE/app/Config/core.php
- Search for next line:
|
1 |
// date_default_timezone_set('UTC'); |
- Once you find the line, uncomment it and set your timezone, for example in my case I am going to use “America/Mexico_City”. Find more information about timezones in this link: https://php.net/manual/en/timezones.php
|
1 |
date_default_timezone_set('America/Mexico_City'); |
That’s it!

Git, knowing a better world! a.k.a. “why I love Git”
Probably, some of you know the story of two British salesmen who were sent to Africa in the 1900’s to see if there were any opportunities to sell shoes. The salesmen wrote telegrams back to their colleagues in Britain and one of them wrote, “Situation hopeless. They don’t wear shoes.” And the other salesman wrote, “Glorious opportunity. They don’t have any shoes yet.”
– From the script of Benjamin Zander in TED conferences.
Something similar happens in the development area, in particular in the Version Control System (VCS), because if we don’t use Git yet, that only means we have a tremendous opportunity to use one of the most powerful tools we have currently, save a lot of time in managing code and be happy with a better workflow.
I consider myself a person who always is searching, learning and implementing new ways to create code, so, when I started to learn about how to improve my workflow and quality in development introducing a VCS -some years ago- , my first choice was SVN (maybe, because that one was the only one available for me at that moment). Last year, after taking some courses and listening a Linus Torvals’ conference, I decided to start to migrate my personal repositories into Git…
After testing and using Git, I would like to say I really loved it, it was easier to understand than SVN or CVS, it allowed me to manage my repositories in a better way and saved me a lot of time (let’s face it, I didn’t enjoy the merging process in CVS for CNH projects).
But, maybe my favorite feature in Git -and its platforms- is that Git was created to be totally social and express the sense of community; let me tell you about it: when I heard about platforms like Github, Bitbucket (or Stash) by Attlassian, I realized Git would be the future in the VCS area because it would give us the real sense of teamwork and community and I was right!
Just to give you an idea: at the end of 2013 Github announced the creation of the 10 millionth repository https://github.com/blog/1724-
Now, if you are wondering what is the state of the art in the Enterprise World, well, Atlassian has created two very good tools, one of them is Bitbucket (which I use for personal projects) and Stash which is a kind of the enterprise version of Bitbucket. Stash can be integrated to JIRA (which would improve even more our development).
So, why I am telling you all this and maybe using your time for reading my post?
My answer is simple: because you have to know Git, is wonderful!
In a nutshell, I invite you to learn Git, collaborate in Github community projects and come with us on the way for knowing a better world!
Regards.
How to delete a remote Git tag
If some day for any reason you want to remove a tag because maybe you make a mistake and you want to move your Git tag to another commit, then you are going to need:
- Delete the tag from local repository
- Remove the tag in the remote repository
For doing these operations, just execute next commands:
|
1 2 3 4 5 |
// Delete tag "1.3.0" from local git tag -d 1.3.0 // Delete tag in remote (synchronizing) git push origin :refs/tags/1.3.0 |
BTW, maybe you find this list of Git commands useful for your work: x
That’s it!

Some online editors for Markdown syntax
If you have worked with Github and you have created some Github pages probably “markdown syntax” is part of your daily work. This great language was created by John Gruber and Aaron Swartz and used in many systems like Github, Atlassian Bitbucket, Atlassian Stash, etc. the nice thing about this language is that it is really simple and light. But, sometimes is difficult to imagine what is going to be the result of a particular statement. So, in order to have a preview of your small Markdown documents, you can use an online viewer, next is a list of them (the order is my own preference):
- http://markable.in/editor/
- http://dillinger.io/
- http://markdownlivepreview.com/
- http://www.markdownviewer.com/
If you want to know more about Markdown, please visit next links:

Session 6: jQuery for the real world (in spanish)
Would you like to improve your skills in Ajax calls and communicate jQuery with other frameworks like CakePHP?, well if you answered yes, this post is definitely for you. This is the sixth and last video of the first part of an initiative related with jQuery that I have named jQuery for the real world. All code and practices can be downloaded from my Github profile: https://github.com/alex-arriaga/jquery-para-el-mundo-real or if you only want to obtain a compressed copy you can use this Github page: http://alex-arriaga.github.io/jquery-para-el-mundo-real/
In this session we will see:
- Inserting data into a database by using an Ajax call
- Method load()
- Creating html selects dynamically (database’s query + generation)
- Multiple Ajax calls (chaining)
- Using Bootstrap JS to display modal messages
